END GATE.

Application, filed April 3, 1925.

To all whom it may concern:

Be it known that we, ELI/[ER T. JAoKsoN and ALBERT E. J AOKSON, citizens of the United States, residing at Fullerton, in the county of Nance and State of Nebraska, have invented certain new and useful Improvements in End Gates, of which the following is a specification.

This invention relates to wagon end gate structures and pertains particularly to an end gate having an automatic locking and releasing mechanism.

The primary object of this invention is the provision, in a manner as hereinafter set forth, of a vertically movable wagon end gate having improved means for latching and unlatching the same when an actuated cable connected thereto is drawn.

Another object of the invention is the provision, in a manner as hereinafter set forth, in a wagon end gate of means acting to prevent material carried in the vehicle to which the gate is applied, working its way between the gate and the wall of the recess or guide way in which the gate is held.

The invention contemplates the provision of a pair of spaced vertical channel members adapted to be secured at the rear of a wagon and to extend above the same. The sides of the gate are adapted to reciprocate in the channels of these members and connectcd across the top of these channel memhers is a supporting bar carrying a pair of pulley members. Through these pulley members a flexible cable passes and is connected at a point near the lower edge of the gate in the central part thereof, to the arm of a cam member which member acts, when swung by the cable referred to, upon a pivoted arm to swing the same, this arm in turn acts to draw inwardly a pair of latched members which normally act to lock the gate in position. Continuous pulling upon the cable referred to acts to raise the gate in the channel members to open the end of the wagon.

A final object of the invention is the provision, in the manner as hereinafter set forth, of a wagon end gate structure and locking and releasing means therefor, which is simple in operation, strong and durable,

easily and quickly installed and inexpensive.

tailed description taken in connection with Serial No. 20,459.

the accompanying drawings forming a part of this specification, with the understanding so, long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

wagon body of ordinary construction, nu-

meral 2 indicates the bottom thereof and?) represents the end gate of the wagon.

Secured against the inner face of each side 1 of the wagon adjacent the rear thereof, is

a vertical steel channel 4. The open or channel sides thereof face inwardly, and each of the members 4 extends a substantial distance above" the wagon body as shown. Connected across the top ends of the members 4: is a supporting beam 5, having its ends riveted asat 6 tothe members 4.

The gate 3 has, as shown, a reinforcing channel iron 7 fitted over and extending throughout the length of each side edge. These side edges of the gate 3 are positioned in the channels of the members 4 as shown in Figure .4, and the gate is adapted to reciprocate vertically in these channel guide ways.

Each of the channel irons 7 upon an edge 1 of the'gate 3 has a plurality of studs 8 projecting from the face'thereof and upon each of these studs 8, a friction roller member 9 is pivotallymounted to work in the channel 7 to increase the ease with which the gate may be raised.

Upon the outer face of the gate 3 there is secured by appropriate securing means, a pair of obliquely crossed angled reinforcing bars 10. Mounted at the point where the'said bars cross, which is upon the vertical center of the gate 3 and below the horizontal center thereof is a swinging arm 11, this arm being pivoted by means of thebolt or pivot pin- 12 which extends through the reinforcing bars 10 'as shown in Figure 3. The arm 11 is pivoted at a point adjacent one end thereof and at points equidistantly spaced upon each side of the pivot point 12., the apertures 13 are formed through the arm. The lower end of the arm is free'to swing. I 7

.Upon the upper end of each of the reinforcing bars 10 is a housing 14 and casing spring member 15 which surrounds the shank 16 of a securing latch :or bolt 17, the head 18 of which is sharpened as shown and engages in a notch formed in the adjacent channel members 4. -The spring abuts the rear port-ionof the latch 17 and normally acts to maintain the latch in aforwardly projected position .in engagement in the notched channel member. Link 'connecting members 19 connect the rear ends of the shanks 16 with the arm 11;0113 end of each link member 19 engaging in one of the apertures 13 of the arm. I

Pivoted upon the outer face of the gate 3 by the bolt 20, is a cam member 21 having an outwardly and downwardly extending arm 22 formed integral throughout, and this cam21 bears at one side upon the side of the arm 11 adjacent the lower and free end 14 thereof. Suitable space is provided :upon the inner face of the arm 22 to allow for the passage of the arm 11 therebeneath. The outer end of the arm 22 is apertured and has passed therethrough the bolt 23 which extends throughuthe arcuate slot 24 formed in the lower portion. of the .gate 3.

Upon the innerend of the'bolt 23 there is mounted an arcuate plate 25 corresponding in curvature to the curve of the slot 24 and adapted to normally cover the slot at all times. .Overhanging guide ways'26 are provided for the plate 25 to ride in, these guide members being secured to the inner faced the .gate .and the plate guided thereby bear- .ing against the inner face of the gate.

Connected to the inner end of the bolt 23 inside of the plate 25, and by means of attached eye .27, is a flexible cable 28 which extends upwardly across the inner face of the gate .3 to a pulley .29 mounted to revolve upon the inner side of the cross bar 5, and the cable passes on over a horizontally mounted pulley -30 .positioned at the upper endof one of the channel members 4 where 1t passes downwardly beneath a third pul- .ble is then attached to a reciprocating ley 31 mounted upon the side 1 of the wagon body. After passing this pulley 31 the cabar 32 mounted in the guide loops 33 which are secured to the side of the wagon body. The

bar 32 is provided with a series of spaced outwardly projecting pins 34 against one of which a lever pivotally secured as at 36 to the wagon body, is'adapted to bear.

.A uide loo) 3? is also )rovidcd for thc e V l lever 35.

In Figure 6 of the drawing the bar 32 is shown as provided at its terminal end with a hand grip 38, so that the bar can be drawn back by a person standing by the side of the wagon body, as the lever is of the foot operative type adapted to be operated by the driver of the vehicle forcing the lever forward by pressing upon the same with his foot. In view of the foregoing description it will be readily seen that upon press ing the lever 35 forwardly it will contact with one of the pins 34- to draw forwardly with it the bar 32 and the cable. 23. llhcu the cable is thus drawn it will act upon the belt 23 to cause the arm 22 to be lifted.

swinging the cam 21 to cause the same to bear against the freely swinging end of the arm 11 to partially revolve the same drawing upon the links 19 and retracting the bolts and latehmember 17 from engagement with the channel members 4. Continuous pulling upon the cable 18 will cause the unlocked end gate 3 to be lifted vertically in the channel guide ways, opening the end of the wagon.

Extending vertically upon the inner face of the gate 3 adjacent each side thereof is a tongue member 39 the edge of which overlies the adjacent channel member 4 and bears the'reagainst as indicated at 40. This tongue extends throughout the length of the gate '3 and thereby covers the space existing ,between the side of the channel 4 and the grain, from working its way into the channel between the gate and the side wall thereof.

In order to retain the reciprocating bar 32 in a steady position there is provided a plate member 41 which is secured against the wagon body 1, behindthe bar 32 and which has a pair of spaced arms 42 projecting therefrom. Between the arms 42 there is'lodged a spring 43 the outer end of which is covered by the retaining key or plate 44, which has the spaced legs 45 upon opposite sides thereof to straddle the arms 4:2 to prevent it from being turned or lost from the arms. The bar '32 passes over the face of this key 44 and is pressed outwardly against the lever 35 and securely held there against to prevent rattling and displacement, as shown in Figure 5 of the drawings- The top and bottom edges of the gate 3 are finished off by having the bars 45 extend throughout the length thereof and sunk thereinto. The bar 4L5 at the bottom of the gate serves as a wear plate and also acts to maintain a tight oint between the gate and the wagon bottom.

From the foregoing description it will be readily seen that there has been provided a novel as well as a serviceable and substantial wagon end gate, which will be satisfactorily in operation and easy to install or remove from position.
